My first article in
quantum mechanics. Admittedly too verbose, no math. And yet, it's the first to
raise a fundamental question never considered before: Suppose the
relativistic prohibition against faster-than-light velocities didn't exist,
would the EPR experiment cease to be strange? It turns out that some other
oddities exist in the EPR that has not been noticed so far!

Three prohibitions of
physics, namely, i) the relativistic prohibition on superluminal
velocities, ii) the quantum mechanical prohibition on predictability,
and iii) the thermodynamic prohibition on spontaneous entropy decrease, are
dictated by different branches of physics, yet they are mysteriously
related: Transgressing one of them entails transgressing the two others!

The notorious
bomb-testing experiment, to which Penrose has made such nice PR in his books,
and eventually carried out By Zeilinger.

Suppose you have a stack
of super-sensitive bombs, each of them so sensitive that a single photon
suffices to detonate it. Yet some of them are no longer operable. How can you
test them without losing any?

To the best of my
knowledge, this is the only experiment in the history of physics that makes one
smile.

Fancy catching Hawking
in self-contradiction. Few years later Hawking abandoned his information-loss
paradox, thereby escaping the contradiction we pointed out. We do not know
whether he has read our paper or was influenced by it in any other way. Still,
we find his convoluted "resolution" of his own paradox much less
convincing than the simple paradox itself. Time-asymmetry may be independent of
initial conditions, despite Hawking’s recanting.

A new variant of the EPR
experiment. You perform only a partial measurement on one particle – the other
is partially affected, hence the two particles remain entangled, and may
keep "talking" with one another. You erase the result of one
particle's partial measurement, and the result is instantaneously erased in the
other particle. Erasure, just like measurement, exerts non-local effects!

A review and summary of
our quantum mechanical works that yielded several surprising predictions.

Note especially the
Quantum Liar Paradox! Unlike other quantum-mechanical paradoxes (EPR,
Schrödinger's cat, etc.), which point out contradictions between QM and
relativity or Newtonian physics, this paradox presents a feasible experiment in
which the results contradict ordinary logic.

This paper was rejected
off-hand by four journals before being published. Since then other experiments
give further evidence to what seemed to be impossible: Nature discriminates between
left and right even at the molecular level!

Fancy a high-school boy
named Or (Hebrew: "light") who is so conversant in relativity theory
that he became first author of this radical paper on the foundations of special
relativity. Other papers on general relativity are to follow.

The Aharonov-Bohm
effect, discovered in 1959, is one of quantum mechanics’ most intriguing
products, involving an electric current’s influence outside the region it is
supposed to exert it. We study an apparent faster-than-light effect which seems
to follow from the AB effect. The paradox’s resolution is based on a
complimentary phenomenon, the Aharonov-Casher effect, discovered in 1984. The
latter effect is thus re-derived from the former by causality considerations.

You would expect that,
during the 150 years or so since the inception of Maxwell's demon paradox, all
the interesting questions related to it have already been asked. Well, we now
raise two questions which have not been considered so far. The answers seem to
be nontrivial as well.

Hidden variables are for
quantum mechanics what the ether was for pre-relativistic physics: No one can
prove they exist yet many physicists can't think about quantum phenomena
without them. If (and it’s still an if) this paper’s reasoning is correct,
hidden variables may be disproved once and for all!

My first paper on
evolution. It elicited the most abusive article I ever read, by H. Yockey, to
which I replied, more politely. In retrospect I am grateful to the man for
pointing out some essential errors in my thinking, which I believe were
corrected since.

A more mature biological
paper. Why do symmetry and other forms of invariance prevail over all life's
kingdoms?

Remember Plato’s insight
about the primacy of form over the matter in which it is embedded?
Surprisingly, the living organism seem to manifest this very idea! And
thermodynamics seems to offer further support for this characterization of
life.
